Heat curing paint 2 weeks later. Is it too late?
I painted a couple of engine parts (fan and shroud) with Rustoleum High Heat Paint rated for 1200 degrees about 2 weeks ago. They won't be installed for another couple months. Meanwhile, I spoke to the manager at Rustoleum and he informed me that I was supposed to heat cure the items an hour after the last coat, but that is not instructed on the can. He said it must go up to 350 degrees for an hour to cure it. Wish they wrote that somewhere.
My question is: Can I heat cure 2 weeks later when the items have just been sitting or is it a lost cause and I need to strip and sandblast again? The fan was painted aluminum and the shroud black.
